Moko battery kit for Xbox One controller is an affordable alternative to Microsoft's official option

An affordable alternative to batteries.
Microsoft's official play and charge kit for the Xbox One controller is very good, and it's a definite improvement over having to swap out batteries every time the control pad dies. The fact the Xbox One controller doesn't just have an internal battery like Sony has on the DualShock 4 is disappointing enough in itself.
The only drawback to the official kit is that you have to charge the battery inside the controller. Without an external charger, you can't stack multiple battery packs and have a fresh one ready to go when you run out.
That's where this third-party kit from Moko has an advantage.
